Redis Performance Skill

Memory Management

maxmemory 4gb
maxmemory-policy allkeys-lru
maxmemory-samples 10

Eviction Policies

Policy	Description	Use Case
noeviction	Error on full	Critical data
allkeys-lru	Evict LRU	General cache
volatile-lru	Evict LRU with TTL	Session cache
allkeys-lfu	Evict LFU	Frequency-based

Memory Analysis

INFO memory
MEMORY DOCTOR
MEMORY USAGE key
MEMORY STATS
redis-cli --bigkeys

Slow Log

CONFIG SET slowlog-log-slower-than 10000  # 10ms
CONFIG SET slowlog-max-len 128

SLOWLOG GET 10
SLOWLOG LEN
SLOWLOG RESET

Common Slow Commands

Command	Fix
KEYS *	Use SCAN
SMEMBERS	Use SSCAN
HGETALL	Use HMGET

Benchmarking

# Basic
redis-benchmark -q -n 100000

# With pipelining
redis-benchmark -q -n 100000 -P 16

# Specific commands
redis-benchmark -t set,get -n 100000 -q

Latency Monitoring

CONFIG SET latency-monitor-threshold 100
LATENCY DOCTOR
LATENCY HISTORY command

Key Metrics

Metric	Healthy	Warning	Critical
Memory	<75%	75-90%	>90%
Ops/sec	Baseline	+50%	+100%
Latency	<1ms	1-10ms	>10ms
Hit ratio	>95%	90-95%	<90%

Troubleshooting

High Memory

INFO memory
redis-cli --bigkeys

Fix: Set eviction policy, add TTL

High Latency

SLOWLOG GET 10
LATENCY DOCTOR

Fix: Optimize slow commands

Error Codes

Code	Name	Recovery
PERF001	OOM	Increase maxmemory or evict
PERF002	HIGH_LAT	Check slow log
PERF003	FRAG	MEMORY PURGE or restart
